IMPROVEMENT IN APPARATUS FOR CONDENSING COAL-OIL.

Specification forming part of Letters Patent No. 24,561, dated June 2:, 1859.

T0 at w/wm it may concerm Be it known that I, WM. G. W. JAEGER, of Baltimore, in the county of Baltimore and State of Maryland, have invented certain Improvements in the Condensation of CoaLOils; and I do hereby declare that the following is a full, clear, and exact description of the principles or characters which distinguish them from all other things before known, and of the usual manner of making, modifying, and using the same, reference being had to the accompanying drawings, of which Figure l is a perspective view of the condensing apparatus, and Fig. 2 a vertical longitudinal middle section through the condens ing-main.

My invention consists in certain improvements in the condensation of vaporsin theprocess of distilling coal-oil, described and repre sented as follows:

The modes of distilling coil-oil now in common use, where the condensation of vapors takes place principally in condensing-worms or tubes, are liable to serious difficulties from the frequent choking of the pipe by the induration of the heavy oils and the difficulty of regulating the temperature of the cooling-water in the tubs, vats, or boxes containing the condensing-pipes, and of keeping the temperature of the water at or near the same degree throughout the tub.

To remedy these evils, and, further, to facilitate the separation of heavy and light oils, I introducebetween the retort and the condensing-worm a large surface-condenser, which I call the condensing-main, the construction of which is as follows: The main is constructed with two concentric cylinders, a b, and

a coldwater pipe, 0, which connects with the water-space e by the pipe d. The water-pipe rises to a suitable elevation, f, to receive the water from any convenient source. The water passes through and out from space 6 by the overflow-pipe g,and the flow or overflow of the water can be regulated to any required amount by the ordinary appliances used in such cases. The chamber h within the inner cylinder, 1), and around the pipe 0 is in communication with the coal-retort by means of thelarge pipe or opening 17, it not being necessary to exhibit able oils are there condensed and discharged.

through the pipe 1), while the vapors of the lighter oils pass over through the funnel'm, and any heavy oils that may be condensed in this funnel are returned to chamber h by means of the inclined surface it.

It will be seen that the action of this condenser is quite different from that of the wormcondenser. passing down through pipe d and upon either side through space 6 is kept at nearly a uniform temperature throughout, while the water is found always to be cooler at the bottom of the worm-tub than above. After the vapors of the lighter oils pass over to the worm they are there condensed in the usual manner, and the oil run off at the lower end of the worm.

For the purpose of facilitating the passage of vapor through the condenser and worm, and also for the purpose of separating the uncondensed vapors or gases from the oils and conducting them to suitable receptacles to be further utilized, I employ a fan-blower, 20,

connected with a pipe, 00, which has its lower end opening into the lower end of the worm, and at a point just above the trap a. In many instances, where the inflammable gases have been suffered to run off with the coal-oil or escape into the room, serious accidents have occurred,and the odor also is very offensive. The draft of the fan being properly regulated,the gases are prevented from escaping at the trap, and are conveyed away either to a gasometer or forced through suitable condensing media. The draft of the fan is direct in its communication with the retort,and acts to relieve the pressure and facilitate the escape of vapor and its conveyance through the apparatus.

The water entering pipe 0 and I am aware that pumps are used in gas-works to relieve the main, as the gas is obliged 1 The employment of a fan-blower when the same is used to draw the vapors from the retort, in the mannerand for the purposes herein set forth.

2 In combination with the fan-blower or draft so used, the escape-pipe x and trap a, arranged and operating as herein set forth.
